Techniques for Allocating Capacity in Cloud-Computing Environments

2. The computer-implemented method of claim 1, wherein the request to provision the one or more virtual resources comprises a plurality of messages provided incrementally, each of the plurality of messages comprising a subset of user-defined constraints of the set of user-defined constraints for provisioning the one or more virtual resources within the cloud-computing environment.

3. The computer-implemented method of claim 2, further comprising receiving an indication that the set of user-defined constraints has been received in its entirety, wherein the placement data is obtained based at least in part on the indication.

4. The computer-implemented method of claim 1, wherein the set of user-defined constraints are received in a single message.

5. The computer-implemented method of claim 1, wherein the set of user-defined constraints are received in multiple messages.

7. The computer-implemented method of claim 1, further comprising, in response to obtaining the placement data, providing, to the client device, a notification that the placement data has been successfully obtained for provisioning the one or more virtual resources to the plurality of hardware resources in accordance with the set of user-defined constraints.

8. The computer-implemented method of claim 1, wherein the set of user-defined constraints includes at least two of: the number of computing cores, the amount of memory, the amount of storage space, the chipset type, the cost, or the resource density.

10. The computing device of claim 9, wherein the request to provision the one or more virtual resources comprises one of: i) a plurality of messages provided incrementally, each of the plurality of messages comprising a subset of user-defined constraints of the set of user-defined constraints for provisioning the one or more virtual resources within the cloud-computing environment or ii) a single message.

11. The computing device of claim 10, further comprising receiving an indication that the set of user-defined constraints has been received in its entirety, wherein the placement data is generated based at least in part on the indication.

14. The non-transitory computer-readable storage medium of claim 13, wherein the request to provision the one or more virtual resources comprises one of: i) a plurality of messages provided incrementally, each of the plurality of messages comprising a subset of user-defined constraints of the set of user-defined constraints for provisioning the one or more virtual resources within the cloud-computing environment or ii) a single message.
